- This invention relates: to heaters, and is il lustrated as embodied inan-automobile having a heater embraeing-part-of the exhaust it provided-with a portion embracing a part of theexhaustmanifold of, the engine and which is secured in place by being drawn toward the manifold and engine in such a f manner as to clamp it detachably thereto." Inone desirable arrangement the manifoldf -embracing part of the heater isfgenerally g a V r manifold 16 having' atits-center anopen part 1 .18. arranged to register with a: jacket 20 surrounding part of the intake manifold in channel shap'ed' is cross section, and engages at its lower edges respectively a horizontal] flange on the outer side of the manifold 20 and ahorizontal "surface on the engine ad--' jacent the inner side of the manifold, andv attaching devices such as bolts tapped into the manifold are provided for drawing this portion .of theheater downwardly to clamp it detachably againstthe manifold and enme. Another feature of the invention relates; toathe provision, -of a: heater adapted for use withfan engine having an intake '-manifold, and ali'exhaust manifold which jackets a part. of the intake manifold, and in which the heater is arranged to embrace a substantial part of the ex haust'manifold' without enclosing any part of the intake manifold; As the exhaust jacket is usually made integral with the in take manifold in constructions of this character, this arrangement provides a heater which in no way interferes with the removal of the intake-manifold at any time.

The invention also contemplates eflicientlyinsulating the heater from the interior of the vehicle when it is not being used, by closing the shutter or other control device leading into the'vehiele body, and concurrently particular constructions, will ,be apparent.

from the following description of an illus-- trative embodiment shown inv the accom panying drawings, in which Figure 1 is a diagrammatic side elevation of theinternal combustion engine of an intake manifold; arid diverting the heated air away from the-- HEATER;

Figure 1 showinvth'e relation of'thevehicle Heater to. the exhaust jacketed part-f the Figure 2'is-"a'section on the li1'1e 2-,'2. of-

' Figure 3 is a section onitheline as of Figure 1 .showingi-the manner" of clamping the heater against the exhaust manifold. In the arrangement selected for'illustra'- tionthe invention is'embodied in'an. auto-. mobile having an internal combustionengine L 10 provided with-an intake manifold 12 having Vertical Pe 4, to, which the earburetorconnections are'secured; The en ine also has a generallyhorizontals exhaust such-a manneri-as to provide what is sometimes called. ahot spot."fl'The. exhaust manifold 16 communicates injthe'usualnian- I nor with a-conduit 22'leading to themuflier.

In'Figure 1 is shown part of the floor board g i 24 andfthe lower part of thedash 26.

The -present invention relates to a vehicle novelty comprises the use of means for"di-,

,verting the. heater air from the shutter when it is elosed,'to prevent undesirable heating of J the floor board,"'as by an auxiliary shutter 29 connected to shutter '30 by links 31in such a manner that it is infull-line position (Figure 1')'whensh-utter30 is openyand is in dotted'line position when shutter '30 is auxiliary shutter 29 is in dotted line position,

opening in the top of the part 28 of the heater. F orwardly of the funnel shaped portion closed. will be evident that when the f the heated air will be diverted through an 28 the heater is'in the form of a channel horizontalflange 34 on the outer face of the exhaust manifold 16 at opposite sides of,

jacket 20, and is arranged at its center .to"

engage the top face of the part 18 of the exhaust manifold as shown in Figure 2 so that no part of the intake manifold or its' jacket lie enclosed in the heater, and consequently the intake manifold can be removed by taking out the attaching bolts 36withoutdisturbing the heater. .The in-- *ner lower edge of the portion 32 of the heater rests on a horizontal surface adjacent "and parallel to the inner face of the exhaust manifold '16 and which is formed as aledge along the edge of-the cylinder head 38 of the engine 10. The portion 32 of the heater is'preferably also provided with a partial bottom closure or flange 40 bridging the space between the cylinder head 38 and the. inner face of tl1e'.exhaust m'anifold16, 18.

The heater is" clamped detachably in place by draw bolts 42 tapped into the upper face of the exhaust manifold and which carry wing nuts 44 for drawingthe heater downfins are inclosed by the heater.

It will beseenthat the construction described is suitable for manufacture in large quantities at a low cost, of sheet metal, and

that it is in one single piece without horizontal or other joints.

Moreover, it can very, quickly and easily be attached and detached by means of the draw bolts 42 and the wing nuts44.

While one illustrative embodiment of the invention has been described indetail it is not my intention to limit its scope to that partcular embodiment or otherwisethan by ,the terms of the appended claims.

I claim: V 1. A heater' for vehicles comprising an internal combustion engine having an exhaustmanifold provided with an opening,

an intake manifold having a jacket engaging the opening, a heater casing enclosing the upper part of-the exhaust manifold and engaging the wall of the exhaust, manifold" Within the line of junction of the jacket andexhau'st.manifold to permit the removal of :the intake manifold ith ut removing, the.

heater casing, v

2. A heater for vehicles comprising an internal combustion. engine having an exahsut manifold, the'exhaust manifold havingan opening, an'intakemanifold provided with a acket engaging the openingofthe exhaust manifold, a U-shaped heater casing enclos ing the'upper'part of the exhaust manifold and engaging by its outer wall the horizontal part of the exhaust manifold, the engage manifold having the opening being Within the line of junction of the intake jacket with ment of the casing at'that portion of the the exhaust manifold to permit the removal of the intake manifold without removing the heater casing.

3. A heater for vehicles, comprismg a U-shaped heater casing, an internal combustion engine having an exhaust manifold pi'ovlded with an integral supportingflange on-- its outer face extending horizontally of the manifold, said engine also having a horizontal supporting-portion adjacent the inner face of the manifold,thehorizontal support ing portion of the engine and integral horizontal flange of .the manifold forming seats upon which said 'cas1ng .rests, and a hold downbolt extending vertically between the manifold and casing, and being adapted'to.

downwardly clampsaid casin g on its seats.

4. A heater for vehicles, comprising a U-shaped heater casing, an internal combus-- tion engine having an exhaust manifold, provided with an integral supporting flange. on a side wall and extending horizontally thereof, and on which a lower marginal edge of the casing rests, and vertically extending hold-down connections adapted to draw said casing:downwardly and hold the se ne upon said horlzontal supporting flange.

In test-nnony whereof I aflin my signature.
